SPECIFICATION forming part of Letters Patent No. 367,417,61ated August. 2, 1887,

Application filed Dt @caber 24 1F86. Serial No. 222,510. (No model.)

.To @ZZ whom, it may concern:

Be it known that I, GEORGE E. LLOYD, of Chicago, in the county of Cook and State ot Illinois, have invented certain new and useful Improvements in Vood-Planing Machines; and I do hereby declare that the following` is a full, clear, and exact description ofthe invention which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part ofthis specification.

The object of my invention is to provide means for adjusting the revolving cutter-carrying heads, and for clamping the wood on the bed of stereotypers and electrotypers woodplaning machines, or, as it is better known to the trade Daniels Plainer,77 substantially as described, andas illustrated in the drawings, in whichh Figure lis a front elevation ofmy invention, showing the bed in transverse section. Fig. 2 is a side elevation thereof, showing the crossbars in section and the standards in dotted lines. Fig. 3 is a plan view, and Figs. 4, 5, and 6 are detail views. K

Reference being had to the drawings, A represents the standards resting on and secured to the table-frame of the machine. Connecting these standards by means of bolts traveling longitudinally through them are the upper and lower cross-bars, a and b, respectively.

The bolt B, connecting the cross-bar a to the standards A, is eccentric-that is, the portion ot' its barrel located within the bar a is of one diameter, whereas the diameter of that part nearest to the head and which rests within the adjacent standard is greater and has its center set a little below the center of the barrel of said bolt, which lies within said bar a. The end of the bolt resting within the right-hand standard is less in diameter' than the part of the bolt within bar c, and its center is in alignment with the eccentric portion of the bolt contiguous to its head. Y The reason the" eccentric end of this bolt B is less in diameter than the rest of its length is so that it may be set in .position from left to right, which, considering its eccentricity, could not be easily accomplished were it otherwise. The eccentric end of this bolt is screw'threaded and a nut placed thereon to secure it in position. By oscillating this eccentric bolt cross bar a can be moved forward or backward a distance corresponding to the eccentricity of the ends of said bolt. The bolt B, connectingthelowcr cross-bar, b, to the standards, is straight.

Secured by means of screwsto the front surface of bars c and b, about their centers of length, are the bosses C and C. Boss Cis secured to'bar a by means of two screws, c c, which pass through holes in bara, the diameter of which is greater than theirs, as shown in Figs. 2 and 6. Boss C is secured in like manner to cross-bar b by one screw, c', located about the center of said boss and bar. These bosses C and C are provided with vertical central dovetail mortises in their outer faces, in which corresponding tenons from the contiguous surfaces-of the pillows of bearings 0l d enter, and can be moved vertically, as will be hereinafter more fully explained.

Bearings dd are connected by a vertical bar and journal the vertical spindle D, which is provided with a nut and lock-nut on its upper end to retain it in position, a pulley between its bearings, through the medium of which it is actuated,and the cutter-carrying head on its lower end. vertical adjustment, I extend from the upper bearing, d, an auglearm, c, the horizontal part of which projects over the top lof boss C. Passing vertically downward through this arin c is aset-screw,c, which simply limits the adjustment by bearing on the top of boss C; and there is a screw, E, with a balance-handle, which, by' means of the boss or enlarged diameter above said arm c and collar immediately below, carries said arm, bearing, and spindle up or down, according as it is screwed in or out .ofthe boss C. l

Projecting laterally from the upper crossbar, a, at either side of boss C, are lugs g g'.

These lugs are tapped laterally for the reception of set-screws j' f, ythe ends of which bear against the vertical sides ofsaid boss C. When it is-desired to adjust said cutter carrying head laterally, I slightly loosen screws c c and then adj ust screws ff. The spindle is thereby oscillated laterally within the limits of the enlarged holes in the crossebar a, through which said screws c pass. Screw c', securing the In order to give the spindle a IOO lower boss, C', to crossbar b, serves as the point of oscillation when the spindle, &e., are oscillated laterally.

Vhen it is desired to oscillate or adjust the cutter-carrying head in alongitudinal directionwthat is, lengthwise with the bed-thc bolt B is oseillatcd in its bearings in the stand ards, thus, by reason of said bolt within bar c being offset from or eccentric to the center ofoscillation of its journals, moving said bar c forward or backward,as desired, and oscillating the spindle, Jvc., upon bolt B', which passes longitudinally through bar I).

I do n'ot wish to be understood as claiming as new the spindle, the means for vertically adjusting the saine, northe construction of the bearings thereof, for these are old in the construction of Daniel planers.

In order to keep the wood or block upon the bed as it reciprocates longitudinally under the rapidly-rotating cutter-carrying head, I provide agage, F,which consists ol.' abar of metal one side of which is inversely beveled, so as to leave theprojecting edge sharp,whieh reaches across the bed transversely and has downwardly-projecting ends. The inner surfaces of these downturned ends are inversely beveled, so as to correspond to the edges of the bed, as shown, and one end has a setserew passing longitudinally through it, which impinges against the edge of the bed and holds the gage in position, as desired.

In the bed G is a longitudinal central slot, 71., through which passes alongitudiual screw, H, one end of which projects beyond the end of the bed G, and is fitted with a handle, by which it is actuated. On this screw H, within slot h, is a nut, I, as shown in Figs. l and 5. This nut projects up through slot h to the plane of the upper surface of the bed G, and has attached to it the gage-plate k. The side of plate l.: adjacent to gage F is inversely beveled to provide a sharp edge, and both it and the contiguous sharp edge of gage F may be serrated, if desired.

By adjusting gage F on the bed and turning screw II so as to bring gage-plate 7.1 nearer or remove it farther from the gage F, I can accommodate and hold securely upon the bed all sizes ofbloeks it is practicable to plane on the machine.

Vhat I claim as new isl. In a wood-planing machine, the combination, with the spindle, cutter-carrying head, and bearings of said spindle, of the bosses C and C', and eross-bars c aud b, and set-screws ff, passing laterally through lugs r/ 0, projecting from eross-bar a. on either side of boss C, said boss C being secured to bar n, by screws c c, which pass through holes in bar a of a greater diameter, as described, and boss C' being secured to bar b by a screw, c', as and for the purpose set forth.

2. In a wood-planingmachine,the combina tion, with the cutterearrying head, spindle, and beariu gs thereof, of cross-bars a and b, supporting said bearings, standards A, eccentric bolt B, as described, connecting bar a to the standards, and bolt B', connecting bar b to said standards, as set forth.

3. In a wood-planing machine, thecombina tion, with the cutterearrying head, spindle and bearings thereof, of the bosses C and C', supporting said bearings, cross-bars ya and b, screws c c, connecting boss C to bar a and passing through enlarged holes in said bar c, screw c', eonnecti ng boss C' to barb, standards A, eccentric bolt B, as described. connecting bar c to the standards,and bolt B', connecting bar b to the same, and means, as set forth, for adjusting said spindle vertically.

4. In a woodplaning machine, the combination, with cutter-carrying head and means for revolving the same, of bed G, having the longitudinal slot h, therein, scrcwI'Luut I thereon within said slot, gage-plate k, the gage F, cousisting of a bar crossing said bed,having downturned ends, and a screw passing laterally through one of these Lends and impingiug against the edge of. the bed, as and for the purpose set forth.

5. rIhc combination, with the cutter-carrying head, spindle D, and bearings d d, connected-by a vertical bar and adjustable verti cally by means of an arm projecting from the upper bearing, d, and a set-screw passing down through said arm and supported by cross-bar c, ofstandards A, cross-bars a and b,eccentric bolt B, passing longitudinally through bar a., and pivotal bolt B', passing longitudinally through bar b,as and for the purpose set forth.

G. The combination, with a cutter-carrying head, spindle D, and bearings d d, connected and vertically adjustable, of standards A, bars c and b, to which said bearings are connected, said bar a having a slight movement longitudinally (or coincident with the length of the bed) and bar b a slight oscillation in the same direction, and means consisting of lugs gg, projecting from bar a on either side of the upper bearing, d, and set-screwsff, for giving said bearing a limited lateral movement, (that is, lengthwise of barca) thereby oscillating spindle l) laterally, which lateral movement is permitted by securing the upper bearing to bar c by bolts which pass through holes in saidbar, ofa diameter exceeding theirs, and securing the lower beariugs,r7, to barb bya pivotal bolt, as set forth.
